Canon has announced an updated version of their compact super telephoto zoom lens. The new EF 100-400mm f/4.5-5.6 L II USM boasts a number of upgrades over its predecessor, which Canon claim improve both the image quality and handling of the new version. We preview what this latest lens has to offer and see how the original version performed in the DxOMark Lens tests.

With a full-frame 18-Mpix CMOS sensor and twin Digic 5+ processers that’s capable of continuous bursts of up 12 fps – the fastest of any professional DSLR currently - the Canon EOS-1 Dx is the firm’s flagship press camera. We’ve assessed it with over 100 EF mount lenses, to see how well they perform. Read on to find out which models are the best optically and which, if any, you should avoid.

In the first part of our comprehensive lens recommendations for the new entry-level Canon EOS Rebel T5 / 1200D, we’ve assessed a raft of primes from both the maker and third parties to see how well they perform on the camera. As well as highlighting the best performers we’ve also taken a closer look at the best on a budget.

A favorite of wildlife and action photographers, Canon’s EF100-400mm f4.5-5.6L IS USM is a well-specified and versatile model. However, as it approaches sixteen years in production, is it still capable of competing with more modern offerings? Read on to find out.

Introduced in July this year, the EOS 70D at first sight seems like a regular update to the maker’s mid-range EOS 60D model. It shares a number of features with the firm’s existing SLR range including a 19-point cross-type phase detection AF system, a 3-inch (1.040M dot) articulated touchscreen and built-in WiFi connectivity with remote viewing and image transfer. The camera can also shoot at up to 7fps and has 1080/30p video recording with stereo sound using an optional external microphone.

As arguably the most versatile model in Nikon’s range of telephoto lenses, the 200-400mm f/4 is very popular with professional users and enthusiasts alike. At a shade under $7,000, however, it’s quite a substantial investment. Read on to see if how well this highly regarded and versatile lens performs in our labs.

In this regard the Canon's capabilities make it unique among top-end super-telephoto zooms. For example the Nikon AF-S Nikkor 200-400mm f/4G ED VR II doesn't have the built-in extender (but is half the price), and the Sigma APO 300-800mm F5.6 EX DG HSM is even larger and heavier, but lacks image stabilisation or weathersealing. This doesn't excuse the 200-400mm's price, but it does go some way to explaining why Canon feels justified in asking it. From our point of view, the absolutely stellar optics and innovative design earn the lens our top award.

First seen at the Olympics in London in 2012, the Canon EF 200-400mm f/4 IS USM Extender 1.4x is a pro-oriented super-telephoto zoom with a built-in 1.4x tele-converter. Engaging this extender converts the zoom into a 280-560mm f/5.6 on a full frame camera, making this one of the most versatile lenses in the firm’s line up. Read on to see how well this $11,800 zoom performs with- and- without the 1.4x converter engaged while mounted to the Canon EOS 5D Mk III.

Why is this reviewed so promptly when the Sigm 120-300 OS, e.g. is not only reviewed, but that its review is promised every month and this is a lens which will sell much more than the Canon 200-400?I suspect that there's something fundamentally wrong with your approach when you don't rate the 200-400 as highly as others.
